New Zealand is yet to win at the Las Vegas sevens, having finished second three times at the tournament.

Tietjens said his team is well prepared for the tournament, which has been brought forward this year to before the Wellington Sevens, a first for the World Series.

"In the past we've been a bit underdone coming into Wellington because of the gap between the last tournament.

"This time, with the national sevens having just been played, we're actually in pretty good shape for Las Vegas, and we'll be in better shape than normal heading into Wellington, which is great for our home tournament."
